Subtraction final

I recently bought a new iPad. I partially use the iPad as a second screen when I'm coding (mostly portrait mode for either terminal or Chrome developer tools). However to do so I need to have some kind of holder to put it into.

For now my subtraction final mostly consists of research. I'm still waiting for my Silhouette kraft/craft knife. I am to make this project with brass wires similar to some of the freeform circuits.

For my mid-term project I made this wooden wallet which has a voronoi pattern on the top. I wanted to make another pattern, so I started looking for mathematical patterns.

## Texture

Simple symmetry

These examples above are simple symmetries. They are perfect patterns. I explored pattern number 6 further in Illustrator (see below), however it proved to be quite difficult to make this pattern as perfect as it is in this picture. I also love pattern 3 and 8. But not for this project.

These li symmetries got their patterns through external nature forces. For instance the repeating motion of the tides causes a pattern in the beach sand. Some of these patterns are semi-patterns such as the soap bubbles. Although they look very nice, they might be a bit too ambitious to make these ones by hand. These might however become more feasible again once I can get my hand on a CNC-machine. I bought a book specifically on Li symmetry for more inspiration (David Wade, Li: Dynamic Force in Nature).

## The general idea

Underneath is a sketch with the basic idea. Two rectangular pieces of 12 cm broad and 4 cm high form the front and bottom. These pieces are hold together by 4 crosses. They have an angle of 45 degrees so the iPad doesnt slip away. One part that has to wait till the Fall would be a wooden bottom. This will add some weight to the piece and it also makes sure that it doesnt slip away that easily.

## Template

Here's the template file. The thick lines have a diameter of 1/8 inch and the thinner lines have a diameter of 1.5mm. I will print it using a laser printer and put the wires on top of it. One option would be to go for another voronoi pattern.
